+docker build -t priobike-photon . && docker run -p 2322:2322 --rm priobike-photon
+```
+
+## API and CLI
+
+Use the geosearch:
+```
+curl "http://localhost:2322/api?q={searchstring}&lat={positionLat}&lon={positionLon}&bbox={minLon},{minLat},{maxLon},{maxLat}&lang=de&limit=10"
+```
+
+Use the reverse geocoding:
+```
+curl "http://localhost:2322/reverse?lon={longitude}&lat={latitude}"
+```
